Don't let winter weather stop you from running.Designed to help keep you warm and dry, the ROAD WINTER HIGH WAIST TIGHT was created with brushed knit to retain warmth and to repel wind where you need it the most. For these cold days, we added a waist back pocket and side thigh pockets for phone and key storage. ASICS expert running team recommends using the tight when temperatures drop below 5 degrees C or 40 degrees F.At least 50% of the garment's main material is made with recycled polyester to reduce waste and carbon emissions.
